What group of elements can have more then 1 oxidation number?
Predominantly, the transition elements, but also hydrogen, nitrogen, and oxygen. Actually all elements that have reactions can have more than one oxidation number in the sense that their oxidation number is 0 when they are in pure form and usually is some other value when they are in compounds.
Do all elements in a group have the same oxidation numbers?
There is at least one oxidation number shared by all the elements in a periodic table column, but some of the elements may have more than one oxidation number and some of these additional oxidation numbers may not be possible for all the elements in a column.
Where is the oxidation number in the periodic table?
The oxidation number is located in the top right-hand corner of each element box; for many elements there is more than one.
What is the oxidation numbers of alkaline metals?
The question should be either 'alkali metals' or 'alkaline earth metals'. For alkali metals or group 1 elements, the oxidation number is +1 (note. hyddrogen can have +1 and -1). For alkaline earth metals, the oxidation number is +2 In addition all these elements will have an oxidation number of 0 in their elemental form
What is the oxidation number of C in HCOH?
Carbon is directly bonded with two hydrogen atoms and with an oxygen atom. All other elements are more electronegative than carbon. Therefore carbon has oxidation number +4.

Can an element have more than one oxidation number?
Of course they can have.Many elements have several oxidation numbers.
What elements can have variable oxidation numbers are known as known as what group of elements?
Most elements can have more than one oxidation number, but I think you are looking for the transition elements in groups 3 - 12.
Where is the oxidation number in the periodic table?
The oxidation number is located in the top right-hand corner of each element box; for many elements there is more than one.
What do Roman Numerals represent in chemistry?
The Roman numeral in the parentheses is the valence or oxidation of the metal that it follows. Transition elements have more than one oxidation number

Carbon is directly bonded with two hydrogen atoms and with an oxygen atom. All other elements are more electronegative than carbon. Therefore carbon has oxidation number +4.
What are three elements that have more than oxidation number?
Common examples include many nonmetals as sulfur which bears oxidation numbers varying from -2 to +6 in forming compounds. In oxychlorides, the oxidation number of chlorine atom(s) vary from -1 to +7. Many transition elements also bear different oxidation numbers. Copper has two ions: Copper(I) which is colorless and Copper(II) which is pale blue.
Do elements in the s or p block generally have only one common oxidation number while d elements can have more than one possible oxidation number?
pretty much that is correct. although lead (Pb) is and example of of a +2 or +4 element and Arsenic (As) is a +3 or +5 element
When do halogens show 1 and -1 oxidation states?
When halogens bind to more electropositive elements (compared it itself), they show -1 oxidation state. When halogens bind to more electronegative elements (compared it itself), they show +1 oxidation state.
Do elements in the s or p block generally have one common oxidation number?
No, this is not the case. Firstly, a simple substance (pure element) always has oxidation number 0. Then there is the fact that when combining with an element more electronegative than the element in question it will tend to have a positive oxidation number while if the element is more electropositive it will tend to have a negative oxidation number.Nitrogen is a good example:-3 in NH3-2 in N2H4-1 in NH2OH0 in N2+1 in N2O+2 in NO+3 in NaNO2+4 in NO2+5 in HNO3Other elements are not as versatile as nitrogen, but a typical non-metal will show all odd or even oxidation numbers over a range of 8 units, as well as zero, while a typical metal will show all odd or even oxidation numbers between 0 and its valence.The elements that do show only one common oxidation number (other than zero) are all of the s-block elements and fluorine and oxygen.
